Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/string.h`, `linux/parser.h`, `linux/timer.h`, `linux/fs.h`, `linux/blkdev.h`, `linux/blk-integrity.h`, `linux/slab.h`, `linux/spinlock.h`.
• Detected declarations: `function iblock_attach_hba`, `function iblock_detach_hba`, `function iblock_configure_unmap`, `function iblock_configure_device`, `function iblock_dev_call_rcu`, `function iblock_free_device`, `function iblock_destroy_device`, `function iblock_unplug_device`, `function iblock_get_blocks`, `function iblock_complete_cmd`.
• Atlas domain: Driver Families / drivers/target.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
